SAMUEL S. GREENE, OF LOWELL, MASSACHUSETTS.

HORSESHOE MACHINERY.

Specification of Letters Patent No. 7,772, dated November 12, 1850.

To all whom z5 may concern Be it known. that I, SAMUEL S. GREENE,ofLowell, in the county of Middlesex and State 0f Massachusetts, haveinvented-a new Combination of Machinery for Making Vrought-Iron orMetallic Shoes for Either Horses or Oxen; and I do hereby declare thatthe same is fully described and represented in the followingspecifications and accompanying drawing', let-ters, iigures, andreferences thereof.

Of the said drawings Figure l denotes a side elevation of my saidmachine. Fig. 2 is a front end elevation of it. Fig. 3 is a vertical andcentral section ofthe two dies. Fig. 4 is an underside face view of theupper die or dies. Fig. 5 is a front or face view of the lower die ordies. 'Fig'. 6 is a rear side View of the lower die. Fig. 7 is a sideview of the two dies. Fig. 8 is a face view of the lower die for oxshoes.

In the said drawings A represents the supporting frame of the machine, Bthe driving shaft having a driving pinion C placed or fixed on it thesaid pinion being made to engage with a gear wheel D fixed on ahorizontal shaft E on which is another gear wheel E made to engage witha gear wheel F of the same size fixed on another horizontal shaft G allas seen in Fig. l. On the outer or front end of the shaft E is a beveledgear H which is made to engage with another beveled gear L affixed on avertical shaft K arranged as seen in Figs. l and 2. The two shafts G andK may be termed the die shafts because they respectively support the dieor dies L and Mv which are disposed with respectto each other as seen inFigs. 1 and 2. These dies are to be so formed that while rollingtogether they may by the assistance of other combinations which will bedescribed in the following not only bend a piece or bar of iron orstripofl metal into the curve of a horse shoe, but at the same timemakes the usual creases and stamps for the holes nearly through, at thesame time it is bending or curving. One of the lower descensions of thefianch a b 0 of the upper die commencing at the curved part (Z of thelower die and both revolve until the descension on the opposite side ofthe upper die meets the curved part cl of the opposite side of the lowerdie and gives the shoe its requisite form which is particularlyrepresent-ed in Fig. 7 which is a side elevation of the two dies L andM. The bar of iron when introduced between the dies is supported on aroller u which carries the bar of iron up against the under side edge orface of the tlanch of the upper die. The bar then lays edgeways ornarrowest way up and sideways against the face of the middle edge of thelower die z'. The other side of the bar against the part g of the upperdie. outer edge of the part z' which is the irst vertical part of thelower die and the under edge or face of lthe flanch is the part thatforms the outer edge of the shoes. The lower vertical edge of the lowerdie forms the inside edge of the shoes. The bar is then caught betweenthe two dies L and M.

By means of the chisel projecting from -the face of the lower die andoperating against the part g of the upper die the first heel of the shoeis squared off and as the dies revolve the shoe is curved and at thesame time coming in contact with the creaser and punches both togetherforming the projection c which creases and stamps t-he holes through ornearly so-when at the full ascension of both the dies which will be atthe part of the upper die. Then the iianch of the upper die descends tothe curved part (l.

on the opposite side of the lower die pressing down the bar of iron orstrip of metal against projection and against projection y these lastprojections finish the last half of the shoes in the same way that thefirst mentioned ones do their work by operating against the part g ofthe upper die, and the i'la'nch of the upper die to curve the shoes asthe dies revolve. The shoe after it receives the pressure of the dies atthe place where they act together and upon it is kept against the lowerdie and from curling or bending out of shape by means of the presser orpressure bar R which is an upright bar on the rear side of the diessupported on a spring T which forces it upward and against two springs,s, t, which press it toward the dies. The bar carries or has attached toit a plate u which projects from it and by means of the two stands onwhich it slides and the three springs it is pressed against the faces ofthe dies and against the outer edge of the shoes and is allowed to moveboth upward downward and laterally, as circumstances may require. Theredie and is attached to spring CZ o side at the curved part the lower dieand revolves round with the dies. Soon after the shoe leaves the plate uon the face of the lower die the piston is carried against and over orupon ya cam K and forced forward by the same and against the first heelend of the shoe and presses it off from the die and upon a curved pieceof metal, t, which is placed close to the face of the lower die andremains stationary and as the dies` revolvel the shoe runs down over itand is released from the dies when the second piston h throws out thelast heel end of the first shoe. This shoe as will be seen has occupiedv one half of the die and as the die finishes its revolution a secondshoe will follow in the same manner of theffirst one from ofi the otherhalf of the die. Thus making one or two shoes at each ent-ire revolutioncreased, stamped, and in perfect shape for the hoof, as abovesubstantially specified.
